使用linq groupby获得最大值

如何解决使用linq groupby获得最大值

我有一个表ConstructionSets，下面的数据如图所示，其中前两行的相同initialrevisionId相同，修订版本不同

然后我使用以下查询查询数据

var constructionSet =_dbContext.ConstructionSets.Include(p => p.AshraeclimateZone)
                                                .Include(p => p.ExteriorWall)                                                          
                                                .Where(p.sourceOfDataId == this._designHubProject.EnergyCodeId 
                                                && p.MassingTypeId == this._designHubProject.MassingTypeId)
                                                .GroupBy(p => p.InitialRevisionId)
                                                .Select(g=> g.OrderByDescending(x=> x.Revision).First()).ToList();

并出现如下错误

错误：

The LINQ expression '(GroupByShaperExpression:
KeySelector: (c.InitialRevisionId),ElementSelector:(EntityShaperExpression: 
    EntityType: ConstructionSet
    ValueBufferExpression: 
        (ProjectionBindingExpression: EmptyProjectionMember)
    IsNullable: False
)
)
    .OrderByDescending(x => x.Revision)' Could not be translated. Either rewrite the query in a form that can be translated,or switch to client evaluation explicitly by inserting a call to either AsEnumerable(),AsAsyncEnumerable(),ToList(),or ToListAsync(). See https://go.microsoft.com/fwlink/?linkid=2101038 for more information.

我正在使用EFCore 3.0

我希望修订的行数更高，并希望从图像中仅获得1st row and 3rd row之类的两行。

任何人都可以让我知道或提出任何建议为什么我会收到该错误，在此先感谢。
